Title: **Dennis L. Manthei: Innovator in Diaphragm Valve Actuators**

Introduction

Dennis L. Manthei, a prolific inventor based in West Salem, Wisconsin, has made significant contributions to the field of electrically controlled diaphragm valve actuators. With a portfolio of five patents, Manthei's innovative ideas have advanced the capabilities and functionalities of valve systems, particularly in automation and calibration.

Latest Patents

Among his notable inventions is the patent for an **Automatically Calibrating Electrically Controlled Diaphragm Valve Actuator**. This actuator employs a stepper motor, which is managed by a controller mechanism to facilitate movement within a diaphragm valve. The actuator is equipped with a reference position indicator, allowing the controller to ascertain when the actuator is at its reference position within the linear stroke. Manthei's method for automatic calibration involves several crucial steps: driving the actuator to a reference position, moving it a specific number of steps, returning to the reference position, and checking for any fallback. If fallback occurs, additional steps are determined and executed to compensate. This iterative process continues until the full closed position of the actuator is known within a predetermined tolerance, enhancing accuracy and reliability in valve operations.
